10.) she needs 5.64, you basically do 2.35 divided by 5 and then you get 0.47 and multiply that by 12

11.) instead of doing 0.47 multiplied by 12 you would do 0.47 multiplied by 10

LekaFEV [45]

Answer:

The expression that comes after solving the two linear equation is independent of variables So , The system of equations has <u>no solutions </u>

Step-by-step explanation:

Given two linear equations as :

2 y - 4 x = 6 .......1

y - 2 x = 7

Or, y = 2 x + 7 .......2

Now, Solving these two equations

Put the value of y from eq 2 into eq1

So, 2 y - 4 x = 6

∴ 2 × (2 x + 7) - 4 x = 6

Or, 4 x + 14 - 4 x = 6

or, (4 x - 4 x) = 6 - 14

i.e 0 = - 8

∵ The expression that comes after solving the two linear equation is independent of variables So , The system of equations has no solutions Answer
